Meso Worlds are worlds that have a diameter of between 5,600 km and 13,600 km.
- The term specifically relates to solid (rocky) planets or worlds.
- It describes a physical characteristic of the world.
Description / Specifications
A very broad term used to describe the general size of a world. A meso world is likely to have a moderate surface gravity, depending on its density and mass.
General size code categories:
- Size Codes 0 or S: Planetoid.
- Size Codes 1-3: Small World.
- Size Codes 4-8: Meso World.
- Size Code 9 or more: Big World.
Probable Orbits
Meso worlds may be located within any region of a system. Meso worlds are occasionally moons of larger rocky worlds or gas giants.
